Adding additional drives to DL 380 G4 with ESXi installed

Hi everyone,

Just need to acquaint myself with the procedure to add two new drives into an existing RAID 5 configuration on a DL 380 G4. The fly in the ointment here is we have ESXi intalled on it. I already put the drives in, but I have to switch them on, and add them in or set them up on their own little RAID. Came close on searching the forums for an answer, but Need to make sure of whatr I'm doing.
